In November 2018, the Commission adopted a notice of proposed rulemaking that proposed to expand the scope of the Commission’s rules governing ESIMs operations to cover communications with NGSO FSS satellites. Comment was sought on establishing a regulatory framework for communications of ESIMs with NGSO FSS satellites that would be analogous to that which exists for ESIMs communicating with GSO FSS satellites. In this context, comment was sought on: (1) allowing ESIMs to communicate in many of the same conventional Ku-band, extended Ku-band, and Ka-band frequencies that were allowed for communications of ESIMs with GSO FSS satellites (with the exception of the 18.6-18.8 GHz and 29.25-29.5 GHz frequency bands); (2) extending blanket licensing to ESIMs communicating with NGSO satellites; and (3) revisions to specific provisions in the Commission’s rules to implement these changes. The specific frequency bands for communications of ESIMs with NGOS FSS satellites on which comment was sought are as follows: 10.7-11.7 GHz; 11.7-12.2 GHz; 14.0-14.5 GHz; 17.8-18.3 GHz; 18.3-18.6 GHz; 18.8-19.3 GHz; 19.3-19.4 GHz; 19.6-19.7 GHz; 19.7-20.2 GHz; 28.35-28.6 GHz; 28.6-29.1 GHz; and 29.5-30.0 GHz.
